An image forming apparatus includes execution units configured to execute predetermined functional processing, and switches to a second power state lower than a first power state. After a user selects priority on power saving or priority on convenience as a condition for switching to the second power state, the image forming apparatus receives a plurality of recovery triggers for switching to the first power state. A number of times of detection of each recovery trigger received is stored. If the user selects priority on convenience, it is determined whether the number of times of detection of each recovery trigger requiring a large power amount consumed by execution units associated with each recovery trigger falls below a predetermined threshold. If it is determined that the number of times of detection of a recovery trigger falls below the predetermined threshold, the recovery trigger may be disabled.
